Supra cables HDMI FAQ

Please note that Supra 1st generation HDMI & DVI cables were replaced by the HF100 2nd-generation range.

Background:
Supra started shipping their "1st generation" HDMI and DVI cables on 30th July 2004, which were available in a variety of lengths from 1m to 15m and in three different terminated versions:
  • HDMI to HDMI
  • HDMI to DVI-D
  • DVI-D to DVI-D
Below, you will find pictures of the 1st generation HDMI and DVI cables:

The following list shows the product features for Supra Digital video cable:
  • 4 screened twisted pairs of silver-plated OFC conductors (with a PE foam insulation layer) improve the High Frequency response for wide-bandwidth and efficient signal transfer
  • Heavy Triple layer screening - 1st layer: Aluminium foil, 2nd layer: Aluminium foil, 3rd layer: tinned OFC screen shield signals from external influences and prevents the digital signal being radiated into nearby components or other cables
  • 0.8 micron thick 24k gold-plated contacts on connectors deliver long term reliability
  • Small form factor cable - diameter only 8 mm, enabling cable to be easily hidden (but note that the cable connectors are factory fitted and hence cannot be removed - they are also larger than 8 mm !!)

Please note that Jenving Technology AB of Sweden, the manufacturers of the Supra HDMI cables, are registered as "HDMI adoptors" with the HDMI Licensing, LLC which is the standards body which promotes the HDMI standard and provides education on the benefits of HDMI to retailers and consumers.

You will note that few other "specialist" cable companies are so licensed, as many buy their cables from third party sources and then pay to have their own branding applied onto some-one else's cables.

IMPORTANT ADVISORY NOTE for users of 1st generation DVI terminated Supra Digital video cables:
The HDMI<>DVI and DVI<>DVI cables work well up to 12.0 metres for standard native resolution 576p (progressive) and 576i (interlaced) but unfortunately we need to issue a warning if using the 12m HDMI<>DVI and DVI<>DVI cables with up-scaling sources at HIGH RESOLUTION (such as 720 progressive and 1080 interlaced).

When we first tested the cables, there were few up-scaled digital video sources on the market and only the standard 576 pixel resolution products were tested during the design phase of the cable, as that was all that was available!

Since then, newer technologies came to market and where the source hardware increases the resolution (up-scales it) beyond the 576 pixel standard resolution, then over say a 12.0 metre length, it is possible that the picture signal will become poor and indistinct. The visible issues one might encounter are as follows:
  • Predominantly green "haze" to picture
  • High level of "sparkles" on screen
  • Lack of sharp image
Obviously, if the image is up-scaled internally AFTER being received in the viewing hardware, then there is no problem - it's only a potential problem when a 12m HDMI<>DVI or DVI<>DVI cable is used FROM an up-scaler that is outputting higher than 576i or 576p resolution.

Meanwhile if using a 8m or 12m HDMI<>DVI or DVI<>DVI cables - ensure that your hardware is running at no more than 576 pixel resolution. (We understand that some other cable companies are facing the same problem).

Note, for HDMI<>HDMI cables, there is no problem, for any length.

UPDATE - June 2005
For DVI signals, (carried over a HDMI<>DVI or DVI<>DVI terminated cable) the transfer quality is perfectly good up to 4m length cables. However, we have also found that some recent "lower priced" DVD players are now available, where the digital video output chip does not seem to support cables lengths longer than 4m, such that our 8m cables show the above mentioned problems with some combinations of products.

Supra in Sweden re-designed the cable and the 2nd generation HF100 cable" does NOT suffer from these limitations.

If any customers have problems with a Supra DVI cable, running DVI signals at high resolution over ANY length, please send us an email, so that we can respond accordingly.

Note, for HDMI<>HDMI cables, there is no problem, for any length.
